The actual attacks that come with proficiencies vary, but that is only relevant if you are using the pet as an explore pet. If you are building mission pets, it doesn't matter which tree you pick (as long as it has stats that align with the stat you want to build up). For strength stat, you can choose wind, earth, and ice (the other three are int based and really good for a pet whose intelligence you want to increase for missions). You want to try and build a squad of dedicated mission pets, at least one that covers each of the stats (health, strength, intelligence, dexterity, and agility). This way you will have at least one pet that can cover those types of missions at a time whenever they pop up (or more than one if you start building a bunch of mission pets for those times a single stat crops up in the list for a bunch of the missions).

It is pretty confusing at first, but you'll get the hang of it.

Well just have a look at what stats the give in the first row
OR at what the first "attack" you get after 5
Prof points use : Magical or Physical
Physical : Strenght
Magical : Intelligence

Some are a bit more complicated, but I prefer to always go
simple, if I build Str, I pick the first one because I like the
Slash attack(love to extra-wounds my ennemies~ XD)

And when I got Int, I pick Fire for FireBall, I love that
attack because it hit two ennemies~ :3

I realized I should bump this, because I truthfully am still looking for spirit flame 'nixis. xD

As far as battling goes, I made my front-liner Seh go into the Light prof tree in hopes that his moves will help heal him. x3x I kinda wonder if I should get a physical damage dealer zzz...

Well I'm making lil "Green pets" Project, just
waiting they're adults and one of my two
Female Zolnixix have Visible Flammes, all
babies from her will Carry Flammes, if you
don't find any more "Fire-Fox" I could send
you one of their, but the Female is just 3 day
old, Generated, so still got to wait she's 18~ owo

Female & Male
What do you think of them?~ <3

Being almost of the same colors, the babies
will be all green, with the Runes changing a
bit as well as eyes, but will look totally like
their parents otherwise~ :3

Aww, so many greens! o: Is that your favorite color or something? 8D;

I'd love to adopt one of the kits from your project. Is there something special with breeding a showing trait with a pet with no trait? o:

Yes Green is my Favorite color, then there's Purple,
then Brown, well along with Green normally~ XD

And apart that the pet have nothing, but is my only
Male Green Zolnixi ATM, not really~ XD

What is sure is that if I breed both pets I showed you
earlier, it's a 100% chance the babies are carrying the
Flammes of the mother~ :3

I guess that what can be nice of a pet without trait is
that if you only want CERTAIN Genetics that the other
parent have, you'll be sure the baby don't gain extra
Genetics, but apart from that, I see no special use~ :3

So the babies will carry hidden spirit flames for sure? o: That's pretty insightful.

Most of the stuff I capture end up having 2 hidden genes or one showing with one hidden, plus the colors are quite...tacky sometimes lol. But I do hope your project goes well~ o:

Yep, always carrying Flammes and if you want better
proof, since I have a kit, I shall always test them and
you can be SURE they'll have Flammes~ ;3
And that I'm not sending you just any random pet~ XD

My main goal is :
Spread the Green pets!~ <3
Because I love Green~ :3
Only pet in my Green Pet Tab to not be Green is my
Mylia, that is kind of Purple, but that's because she
represent my friend Mylia~ XD

I looked through your stables again -- you play(ed) Mabinogi, haven't you? xD
And some of those reindeer-colored carousel Qitaris look adorable!! o:

Mm, speaking of genetic kit, mind if I send you a few more pets to test? ;u; Just ones I newly captured.

*giggles* Played? I still play toooons to Mabinogi~ <3
I'm like 1.5k in total levels now~ XD
Aiming for 2k, so I can beat a friend of mine to the
levels "battles"~ XD
He beat me to 1k, well I'll beat him on 2k~ >:^D
As for those Carousel girls, yes they are adooooorable~
Both are named after two friends, well their Mabi User~ XD
I know both since a while and they're adorable, so I
though those being adorables, they fitted to be named
so~ <3
My BF want a "Physis" to be created and hopefully to have
a "Vales" too, then we'll maybe try to get more Mabi-named
pets~ :3

Just give me the link to those pets, I'll get them, test and
send back~ <3
